Explain the vertex method

One short explanation. This is exam practice, not a course grade.

A quadratic is written as y = ax² + bx + c. Explain how you find the vertex x-coordinate and then turn it into the full vertex (x, y).

Name the formula for x, then say what you substitute that value into.
